If you really knew how little most engineers know about tolerancing and how small .0005" actually is............you'd be amazed.
The reason they specify .0005" is because they can.........not because they are confident that it's absolutely necessary for the component to function. In just about every case, it cannot be necessary for function unless the component is going to operate in a temperature controlled room.
Occasionally we specify .0005" for a tolerance when we want a specific fit to the jet engine part.........it must not assemble at room temperature but must assemble at about 200°F. That forces our hand into tolerances of this magnitude.
